Synthetic Division Calculator
2x3 - 4x2 - 22x + 24 | |
x - 1 |
Determine our root divisor:
Solve the divisor equation x - 1 = 0Add 1 to each side of the equation to get
x - 1 + 1 = 0 + 1
Therefore, our root becomes x = 1

Leading Answer Term = x(3 - 1) = x2
Since the last number in our result line = 0, we will not have a remainder and have a clean quotient which is shown below in our answer:
Answer = 2x2 - 2x - 24

It appears your answer forms a quadratic equation since the maximum power of your result equation is 2 and your remainder is zero. Click here to solve this quadratic equation
How does the Synthetic Division Calculator work?
Free Synthetic Division Calculator - Using Ruffinis Rule, this performs synthetic division by dividing a polynomial with a maximum degree of 6 by a term (x ± c) where c is a constant root using the factor theorem. The calculator returns a quotient answer that includes a remainder if applicable. Also known as the Rational Zero Theorem
